A two-step regulatory mechanism dynamically controls histone H3 acetylation by SAGA complex at growth-related promoters.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Acetylation of histone H3 at residue K9 (H3K9ac) is a dynamically regulated mark associated with transcriptionally active promoters in eukaryotes. However, our understanding of the relationship between H3K9ac and gene expression remains mostly correlative. In this study, we identify a large suite of growth-related (GR) genes in yeast that undergo a particularly strong down-regulation of both transcription and promoter-associated H3K9ac upon stress, and delineate the roles of transcriptional activators (TAs), repressors, SAGA (Spt-Ada-Gcn5 acetyltransferase) histone acetyltransferase, and RNA-polymerase II in this response. We demonstrate that H3K9 acetylation states are orchestrated by a two-step mechanism driven by the dynamic binding of transcriptional repressors (TRs) and activators, that is independent of transcription. In response to stress, promoter release of TAs at GR genes is a prerequisite for rapid reduction of H3K9ac, whereas binding of TRs is required to establish a hypo-acetylated, strongly repressed state.
